inform derived type as a Julia structure

components

Int32 status

return status. See DPS_solve for details

Int32 alloc_status

STAT value after allocate failure.

Int32 mod_1by1

the number of 1 by 1 blocks from the factorization of H that were modified when constructing \(M\)

Int32 mod_2by2

the number of 2 by 2 blocks from the factorization of H that were modified when constructing \(M\)

T obj

the value of the quadratic function

T obj_regularized

the value of the regularized quadratic function

T x_norm

the M-norm of the solution

T multiplier

the Lagrange multiplier associated with the constraint/regularization

T pole

a lower bound max(0,-lambda_1), where lambda_1 is the left-most eigenvalue of \((H,M)\)

Bool hard_case

has the hard case occurred?

NTuple{81,Cchar} bad_alloc

name of array that provoked an allocate failure

struct dps_time_type time

time information

struct sls_inform_type sls_inform

information from SLS
